09:56:45cheatfatevegansk, ping?
09:58:30veganskcheatfate, the problem is that it's an internal file and it's included to another modules and not imported
09:58:52cheatfatei'm using locks.nim
10:00:37veganskcheatfate, I found the solution. doing the PR now...
10:05:04*kulelu88 quit (Quit: Leaving)
10:31:17veganskcheatfate, do you know why ``{.push hints: off.}`` works and {.push hint[XDeclaredButNotUsed]: off.} doesn't?
10:32:08reactormonkAraq, tabs.
10:32:08cheatfatevegansk, this is not very good solution but {.hint[]: off.} must be used
10:33:48vegansk``syslocks`` used partially in ``locks`` and partially in ``rlocks``. so, this solution must be fine

11:00:03reactormonkvegansk, more like issue #4000, the PRs share ids with them.
11:02:32reactormonkvegansk, no zero/point in your FP library? I'm dissapointed.
11:04:14vegansklokien, it's an experiment, but we use it in production :-)

11:23:48reactormonkthe variables names are a bit on the short side, but otherwise it's not too bad.

11:32:41vegansklokien, there are two ``not that big`` projects that are used by our clients. And they don't even know that they are written in Nim :-)
11:34:19veganskfirst was a small tool that imports some information from external sources to one of our product's database
11:36:22lokienwhat's the second one?
11:38:59veganskThe second was more cool :-) The online activation system for some of our prodcts. And it contains the library that is used from C++ and Haskell applications and the server with REST API :-)

19:57:41Guest22743Hello, I've just installed Nim on Windows XP 2002 SP3
19:57:52Guest22743And now I have problem with nimble
19:58:17fredrik92people out there still use XP?!?!? :P
19:58:38Guest22743It is not my main computer :D
19:58:50Guest22743"could not import: inet_ntop", that is the problem
20:00:03Guest22743I found some issues on github and they are solved
20:01:26Guest22743But in fact, I can't use nimble. Maybe building this from sources will help?
20:03:13dom96hey Guest22743
20:03:25dom96are you using Nim 0.13.0 or the latest from Github?
20:03:50Guest22743I have installed nim via installer from site

20:16:10Arrrrhttps://github.com/nim-lang/nimble#nimble-uninstall
20:16:26ArrrrUps, that wont work.
20:16:33ArrrrJust rm -rf nimble
20:17:19dom96Guest22743: just navigate to where Nim was installed, there should be a uninstall.exe or similar file
20:17:27cheatfatedom96, inet_ntop problem it doesn't help
20:17:49cheatfatedom96, latest development version is affected too i think
20:18:00Guest22743Should I reinstall Nim or Nimble?
20:18:00ArrrrIt was fixed on february
20:18:18dom96Guest22743: both, you need to recompile Nimble as well
20:18:21ArrrrGuest, do you know how to clone a repository?
20:18:26Guest22743Yes
20:18:33Guest22743I will try
20:18:48ArrrrThen https://github.com/nim-lang/Nim#compiling
20:20:18cheatfateArrrr, ws2_32.dll (windows xp) doesnt have export symbol "inet_ntop"
20:21:00dom96cheatfate: yes, but its usage was fixed (I think?)
20:21:12ArrrrThe issue with windows xp was that you could not execute any nim application using sockets.
20:21:23ArrrrNow it works, but i think it doesn't support ipv6
20:22:23cheatfatehttps://github.com/nim-lang/Nim/blob/devel/lib/windows/winlean.nim (lines 836-838)
20:23:58ArrrrThere was an annoying warrning there, but it got fixed recently too
20:26:29cheatfatemaybe "symAddr" can produce this "could not import: inet_ntop"

22:04:38VarriountAraq: Are arrays handled by the generics matching code?
22:05:24VarriountI ask because I figure the best way to find the faulty piece of code is to figure out where an error is *supposed* to happen, and figure out why it isn't.
22:05:43VarriountSo I need a test case that actually works.
22:08:21AraqVarriount: it works properly (aka doesn't compile) when it uses arrays directly
22:08:31Araqbut fails when the array is wrapped in a generic
22:11:44VarriountAraq: Wouldn't that be part of semAsgn?
22:14:29*desophos joined #nim

22:52:34cheatfatei dont like this javascript based editors
22:53:29Varriountcheatfate: Yay! Another compatriot!
22:53:32fredrik92Hmm... Could be nice to write VSIX for Visual Studio to make Nim projects! ;-)
22:54:33fredrik92actually you could probably speed up compile time this way, since Visual Studio automagically uses incremental build and so on...
22:55:34cheatfatefredrik92, but this depends on compiler, not editor
22:55:44fredrik92true
22:56:04fredrik92You, could also write a Makefile! ;-)
22:56:56fredrik92I'm just (obviously) a Microsoft/Visual Studio kind of guy! :P
22:57:32fredrik92Btw, can we get Nim to generate C# code?
22:57:51VarriountAraq: As a side note, is Nimsuggest supposed to spit out "template/generic instantiation from here" for correct files?
22:58:03Varriountfredrik92: You can build a backend. :D
22:58:20cheatfatethe best visual studio was Visual Studio 6.0, all vs after it just made it slower and slower
22:58:35cheatfatebut ms made vs2015 a little faster than 2013
22:59:42fredrik92Well, I mainly do C# nowadays, so VS is still the most awesome IDE for that (that I know of)
23:03:48fredrik92But yes, VS does require a LOT of resources! :-/
23:05:09cheatfatei though c# programmers hate c programmers so will never join nim society :)
23:06:04fredrik92Well at the UiT in Tromsø, Norway, we actually teach C, since I am a TA there I kind of have to embrace it! :P
